The  monitoring system sends the alert either through email or any other forms of alarms. In other words,  it is simply the subset of the various functions involved within network management. Unlike the intrusion detection system which monitors the external threats to the network, the system is involved in checking the system for the brought about by overloading, malfunctioning servers or network connections.
